Specification ofLetters Patent.

. Patented Nov. 2, 1915.

Application filed November 5, 1913, Serial N 0. 799,350.

To all whom it may concern Be it known that 1, ROBERT R. CoLoLoUGH, acitizen of the United States, residing at Maxeys, in the county ofOglethorpe and State of Georgia, have invented certain new and usefulImprovements in Cultivators, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to new and useful improvements in cultivators andmore particularly to cultivator-s designed with spring teeth, the objectof the'invention being to provide a cultivator whereby the sets 'ofteethmay be disposed at various angles relatively to each other and are to bepreferably constructed of round metal instead of fiat metal.

Another object of the invention is the pro vision of a cultivator of theabove character which will possess advantages in points of efliciencyand durability, is inexpensive of manufacture and at the same time issimple in construction and operation.

With the aboveand other objects in view,

the invention "consists in the novel features of construction and thecombination and arrangement of parts to be hereinafter more fullydescribed, pointed out in the claims and shown in the accompanyingdrawings, in which Figure l is a top plan view; Fig. 2 is a sideelevation; Fig. 3 is a sectional view taken on the line 33 of Fig. 1;Fig. 4 is a sectional view taken on the line 44 of Fig. I; Fig. 5 is adetail section taken through one of the securing bars illustrating'themanner of retaining the spring teeth in position; and'Fig. 6 is a detailview illustrating the manner of supporting the teeth from the rear setof bars.

Referring more particularly to the draw ings, 1 indicates the centerbeam to which is secured the handle members 2 whereby the same may bereadily guided. Arranged upon the under face of the beam adjacenttherearend thereof is a plate 4 which is substantially, rectangular inform and is secured to the beam'by means of the bolts 5 which extendupwardly through the beam and secure the transverse elongated plates 6to thetop face of the beam. The plates'6 are 1 arranged in spacedrelation and are preferably disposed above the lower plate 4 at a theirinner ends upon the bolts 7 are the normally disposed parallel bars 8and 9. The transverse bars 8 and 9 arearranged upon opposite sides ofthe beam 1 and are adapted to support the cultivator teeth 10. The bars8 are arranged upon opposite sides of the center beam 1 are preferablychannel form in cross sectlon and are provided at one end with thespaced ears 11 which are arranged upon opposite sides of the bottomplate 4 and pivotally secured by means of the bolts 7.

The outer ends of the bars 8 and 9 are securely held in parallel spacedrelation 'by means of the pivoted brace 2 members 12, the ends of whichare loosely connected to each of the bars to retain them in theiroperative position.

In securing the cultivator teeth 10 in position, I prefer to have theirinner ends looped and mounted upon the transverse 'pins'l3 which extendentirely through the channel bars 8. The medial portions of the teeth 10are supported by means of the eyes 14 which are pivotally mounted in thebars 9 so that when the bars 8 and 9 are adjusted relative to the centerbeam 1, the cultivator V teeth 10 will also be adjusted simultaneously.

It will be noted that the outer ends of the,

teeth 10 are curved, as shown at 15, so that they will readily engagewithin the ground and it will be understood that the curvature of theteeth may be greater or less than the illustration. The bars 8 and 9 areto be securely held in position by means of the 'brace members 16',theinner ends of which are pivotally mounted upon the bolts 7 and arrangedbeneath the ends of the transverse plates 6, the outer ends of saidbrace members being pivotally secured to the longitudinal bars 8 and 9.

Sleeves 17 are rotatably mounted upon the pivoted bolts 7 and adapted tobe arranged between the ends of the bars 8 and 9 and the inner ends ofthe brace members 1 disposed upon relatively opposite sides of Intestimony whereof I hereunto aflix my the beam and extending between theupper signature in the presence of two witnesses. and lower lates onsaid beam said rods at their forwa id ends being mounted upon the ROBERTCOLCLOUGH' 5 beam in advance of said plates, said upper Witnesses:

and lower plates limiting the vertical move- S. E. WRAY, ment of theplows with respect to the beam. W. O. DURHAM.
